Future of Java 8 Language Feature Support on Android
Future of Java 8 Language Feature Support on Android
Posted by James Lau, Product Manager
At Google, we always try to do the right thing. Sometimes this means adjusting
our plans. We know how much our Android developer community cares about good
support for Java 8 language features, and were changing the way we support
them.
Weve decided to add support for Java 8 language features directly into the
current javac and dx set of tools, and deprecate the Jack toolchain. With this
new direction, existing tools and plugins dependent on the Java class file
format should continue to work. Moving forward, Java 8 language features will be
natively supported by the Android build system. Were aiming to launch this as
part of Android Studio in the coming weeks, and we wanted to share this decision
early with you.
We initially tested adding Java 8 support via the Jack toolchain. Over time, we
realized the cost of switching to Jack was too high for our community when we
considered the annotation processors, bytecode analyzers and rewriters impacted.
Thank you for trying the Jack toolchain and giving us great feedback. You can
continue using Jack to build your Java 8 code until we release the new support.
Migrating from Jack should require little or no work.
We hope the new plan will pave a smooth path for everybody to take advantage of
Java 8 language features on Android. Well share more details when we release
the new support in Android Studio.

NASA Data Suggest Future May Be Rainier Than Expected
NASA Data Suggest Future May Be Rainier Than Expected
A new study suggests that most global climate models may underestimate the amount of rain that will fall in Earth�s tropical regions as our planet continues to warm. Thats because these models underestimate decreases in high clouds over the tropics seen in recent NASA observations, according to research led by scientist Hui Su of NASAs Jet Propulsion Laboratory in Pasadena, California.
Wait a minute: how can fewer clouds lead to more rainfall? Globally, rainfall isnt related just to the clouds that are available to make rain but also to Earths "energy budget" -- incoming energy from the sun compared to outgoing heat energy. High-altitude tropical clouds trap heat in the atmosphere. If there are fewer of these clouds in the future, the tropical atmosphere will cool. Judging from observed changes in clouds over recent decades, it appears that the atmosphere would create fewer high clouds in response to surface warming. It would also increase tropical rainfall, which would warm the air to balance the cooling from the high cloud shrinkage.
Rainfall warming the air also sounds counterintuitive -- people are used to rain cooling the air around them, not warming it. Several miles up in the atmosphere, however, a different process prevails. When water evaporates into water vapor here on Earths surface and rises into the atmosphere, it carries with it the heat energy that made it evaporate. In the cold upper atmosphere, when the water vapor condenses into liquid droplets or ice particles, it releases its heat and warms the atmosphere.
It puts the decrease in high tropical cloud cover in context as one result of a planet-wide shift in large-scale air flows that is occurring as Earths surface temperature warms. These large-scale flows are called the atmospheric general circulation, and they include a wide zone of rising air centered on the equator. Observations over the last 30 to 40 years have shown that this zone is narrowing as the climate warms, causing the decrease in high clouds.
Su and colleagues at JPL and four universities compared climate data from the past few decades with 23 climate model simulations of the same period. Climate modelers use retrospective simulations like these to check how well their numerical models are able to reproduce observations. For data, the team used observations of outgoing thermal radiation from NASAs spaceborne Clouds and the Earths Radiant Energy System (CERES) and other satellite instruments, as well as ground-level observations.
Sus team found that most of the climate models underestimated the rate of increase in precipitation for each degree of surface warming that has occurred in recent decades. The models that came closest to matching observations of clouds in the present-day climate showed a greater precipitation increase for the future than the other models.
Su said that by tracing the underestimation problem back to the models deficiencies in representing tropical high clouds and the atmospheric general circulation, "This study provides a pathway for improving predictions of future precipitation change.�
